更强大的“光子芯片”或将问世
2019-10-14 作者: 萧潇 来源: 经济参考报

  近日,哥伦比亚大学应用物理系助理教授虞南方(Nanfang Yu)博士率领的研究团队,利用纳米天线,成功地发明了一种能够在狭窄路径(即“波导”)中,对光线传播进行高效控制的新途径。

  相比于依赖电子进行数据传输的集成电路来说,光子集成电路(IC)主要利用在波导中传播的光线进行数据传输,而打造这类电路的关键在于,对光传播这一过程进行有效控制。虞南方的方法将为人们带来更快、更强大、效能更高的光子芯片。不仅如此,这样的芯片反过来也将为光子通信与光子信号处理带来翻天覆地的变革。

  如何以有效的方式去控制波导中传播的光线?虞南方说,这个问题一直是这一领域最为基础和重要的科学问题。而我们的工作则为这个问题找到了一个革命性的答案。我们所打造的这一个集成纳米光子器件,所占面积是有史以来最小的,但却同时拥有迄今为止最宽的工作带宽。在纳米天线的帮助下,我们能够大大减小光子集成器件的尺寸。

  虞南方的团队发现,对于在波导管中传播的光线而言,最为有效的控制手段是利用光线纳米天线去“修饰”波导管。这些微型天线能够从波导芯片内部吸收光线,改变光线的性质,随后又将这些修饰过的光线释放回波导之中。密集堆叠的纳米天线表现出了极强的累积效应,他们能够在不超过两倍波长的传播距离内,实现诸如波导模式转换等功能。

  虞南方说,“在传统方法中,我们使用的器件长度大多数达到了波长的数百倍。考虑到这一点,我们的研究称得上是一次重大突破。我们已经能够将设备的尺寸减小到原来的十分之一甚至百分之一。”

  虞南方团队打造了一款可将某一波导模式转换为另一波导模式的模式转换器。而这一转换器是实现所谓的“模式分多路复用”(MDM)这一技术的关键所在。一个光波导可以承载一组基础波导模式,以及一系列更高阶的波导模式,正如同一根吉他弦既能弹奏出一个基本音,也可以作为和弦中的一部分。

  MDM这一手段能够大大增强一块光学芯片的信息处理能力。具体来说,在同一根波导管内,人们可以使用颜色相同但是拥有不同波导模式的光线,实现同时传输多个独立的信道。

  虞南方的下一步计划,是将具有主动调节功能的光学材料置入光子集成芯片内部,从而实现对在波导内部传播的光线的主动控制。该装置有望成为现实增强(AR)眼镜的基本组成单元。

  目前,虞南方正与他哥伦比亚大学的同事们就这一项目展开合作。除此之外,虞南方还在探索将波导中传播的波转换为强表面波,在未来,这或许可用作芯片上的化学与生物传感器。
